A Raja sent to Tihar Jail till March 3

In its remand application, the CBI said Balwa's company Swan Telecom (a part of the Mumbai-based DB Realty) allegedly got favours in the spectrum allocation and caused the national exchequer a loss of over Rs 22,000 crore.

It also said Balwa allegedly conspired with private companies to sell to a Gulf firm at a huge profit the 2G spectrum licences Swan Telecom acquired at a cheap rate.

Raja was forced to resign from the Union Cabinet last year after the Comptroller and Auditor General of India faulted him for undervaluing spectrum to favour companies who were largely ineligible for 2G spectrum, and added that the government had probably lost Rs.1.76 lakh crore in estimated revenue.
